A) 8 days
B) 10 days
C) 12 days
D) 18 days
Correct Answer: B
Solution :
Efficiency of (A + B) = \[\frac{1}{8}\] Efficiency of B = \[\frac{1}{40}\] Efficiency of A = \[\frac{1}{8}=\frac{1}{40}\] \[=\frac{5-1}{40}=\frac{4}{40}=\frac{1}{10}\] So, A complete whole work in = [10 days]You need to login to perform this action.
